Metal-polymer Hybrid Nanoparticles for Correlative High-Resolution Light and Electron Microscopy
The combination of fluorescence microscopy and electron microscopy prom-ises a deeper insight into the ultrastructural features of cell organelles, e.g., after drug administration. Both methods complement...
PublicationsDesign and characterization of a plasmonic Doppler grating for azimuthal angle-resolved surface plasmon resonances
We present two-dimensional plasmonic Doppler grating (PDG) for broadband azimuthal angle-resolved nanophotonic applications. The PDG consists of a set of non-concentric circular rings mimicking the wavefronts...
PublicationsOptical coherence tomography with nanoscale resolution using a laser-driven high-harmonic source
The use of extreme ultraviolet (XUV) radiation for nanoscale imaging has dis-tinctive advantages: It is label-free, facilitates high contrast, allows material identification and penetrates opaque matter....
PublicationsCargo-carrier-interactions significantly contribute to micellar conformation and biodistribution
Strategies to deliver drugs using nanocarriers, which are passively or actively targeted to their alleged site of action might favorably affect benefit-risk-profiles of novel therapeutics. Here, we tested...
PublicationsA double self-assembly process for versatile reduced-graphene-oxide layer deposition and conformal coating on 3D structures
In this work we demonstrate a double self-assembly (DSA) process based on the surface interaction between graphene flakes (GFs) and surfactant molecules at water/air interface, leading to the formation...
PublicationsExcitation Power Modulates Energy-Transfer Dynamics in a Supramolecular RuII-FeII-RuII Triad
Multichromophoric arrays are key to light-harvesting in natural and artificial photosynthesis. A trinuclear, symmetric RuII-FeII-RuII triad may resemble a light-harvesting model system, in which excitation...
PublicationsExcited state properties of heteroleptic Cu(I) 4H-imidazolate complexes
The excited state properties of three heteroleptic copper (I) xantphos 4H-imidazolate complexes are investigated by means of femtosecond and nanosecond time-resolved transient absorption spectroscopy...
PublicationsHeteroleptic diimine-diphosphine Cu(I) complexes as an alternative towards noble-metal based photosensitizers: design strategies, photophysical properties and perspective applications
Photoactive Cu(I) complexes are considered as a promising alternative to traditional noble-metal complexes that are mainly based on Ru(II) and Ir(III). Therefore, in recent years heteroleptic diimine-diphosphine...
PublicationsDirected orientation of oligo(phenylene ethynylene)s using ureas or urethanes in rod-coil copolymers
Interchromophoric interactions between oligo(phenylene ethynylene)s incorporated in copolymers in solution as well as in solid state were investigated using UV/Vis and IR spectroscopy. One promising strategy...
PublicationsDetection of Pseudomonas aeruginosa Metabolite Pyocyanin in Water and Saliva by Employing the SERS Technique
Pyocyanin (PYO) is a metabolite specific for Pseudomonas aeruginosa. In the case of immunocompromised patients, it is currently considered a biomarker for life-threating Pseudomonas infections. In the...
